User Terminal Data Backup via Debugging Device Bypass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are unable to back up data from a storage device when the I/O controller of their user terminal is faulty, as existing methods rely on the I/O controller for data transfer.
Innovation Solution
A user terminal design that includes a main controller, multiple multiplexers (MUX), and a debugging device interface, allowing data backup even when the I/O controller is faulty by rerouting data backup instructions through the debugging device, which sends I/O instructions directly to the storage component for backup processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data backup is performed through the I/O controller, then data backup function is available under normal conditions, but data backup becomes impossible when the I/O controller is faulty
Solution Approach 1:
The patent introduces a debugging device as an intermediary component that can directly access the storage component when the I/O controller fails. The debugging device serves as a mediator between the user terminal and storage component, enabling data backup operations to bypass the faulty I/O controller and maintain system reliability.
Solution Approach 2:
The patent implements dynamic signal routing through multiplexers that can switch between different signal paths based on system conditions. When the I/O controller is functional, signals route through it; when faulty, the system dynamically redirects signals through the debugging device, providing adaptability to different operational states.
2Adaptability or versatility
If the system uses a fixed I/O controller path for data transfer, then the system structure is simple, but the system cannot adapt when the I/O controller fails
Solution Approach 1:
The patent implements dynamic signal routing through multiplexers that can switch between different signal paths based on system conditions. When the I/O controller is functional, signals route through it; when faulty, the system dynamically redirects signals through the debugging device, providing adaptability to different operational states.
Solution Approach 2:
The debugging device is designed with multi-functionality, serving both as a debugging interface and as a backup data transfer path. The same debugging device can perform both diagnostic functions and data backup operations, reducing the need for separate dedicated backup hardware and managing system complexity.
